DETAILED DESCRIPTION

In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawings.

Please refer to FIG. 1, FIG. 2, FIG. 3A and FIG. 3B. FIG. 1 is a perspective view of an electronic device according to a first embodiment of the disclosure. FIG. 2 is an exploded view of the electronic device according to the first embodiment of the disclosure. FIG. 3A is an exploded view of a hinge assembly of the electronic device according to the first embodiment of the disclosure. FIG. 3B is another exploded view of the hinge assembly from a different perspective in FIG. 3A. In this embodiment, an electronic device 3 includes a display 30 and a stand 35. The electronic device 3 is, for example, a tablet, a smart phone, a digital camera or a video recorder.

The display 30 includes a first case 101, a second case 102, an assembling plate 103 and a screen 104. The screen 104 has a displaying surface 105, and the second case 102 has a rear surface 106. The first case 101 is installed on the second case 102 to form an accommodation space 107 together. The screen 104 is located inside the accommodation space 107, and the displaying surface 105 is exposed from the first case 101 to the outside. The rear surface 106 is located at a side of the second case 102 facing away from the first case 101. In other words, the displaying surface 105 and the rear surface 106 are located at two sides of the display 30 that are opposite to each other, respectively. The assembling plate 103 is located in the accommodation space 107, and is fixed to the first case 101.

The stand 35 includes a supporting assembly 40 and a hinge assembly 50. The supporting assembly 40 includes a holder 410 and a support 420 that are two individual units. The hinge assembly 50 includes a pivotal shaft 510, a fixing component 520, a first assembling component 530, a link-up component 540, a second assembling component 550, a fastening component 560, a first elastic component 600 and a second elastic component 610. The hinge assembly 50 further includes a plurality of elastic rings 570, a first locking component 580, a second locking component 590 and a reinforcement sleeve 620.

The pivotal shaft 510 includes a first pivotal section 511, a second pivotal section 512 and a limiting section 513. The first pivotal section 511 and the second pivotal section 512 are connected to two sides of the limiting section 513 that are opposite to each other, respectively. In this embodiment, the limiting section 513 is a circular plate with its diameter being greater than the diameters of the first pivotal section 511 and the second pivotal section 512. The first pivotal section 511 and the second pivotal section 512 are coaxial. The limiting section 513 has a first limiting notch 513 a.

Two different parts of the fixing component 520 are securely fixed to the first pivotal section 511 of the pivotal shaft 510 and the assembling plate 103 of the display 30, respectively, so as to fix the pivotal shaft 510 to the display 30.

The first assembling component 530, the link-up component 540 and the second assembling component 550 are all pivoted on the second pivotal section 512. The link-up component 540 is located between the first assembling component 530 and the second assembling component 550. The first assembling component 530 is assembled to the holder 410. The second assembling component 550 is assembled to the support 420. In this embodiment, two sides of the first assembling component 530 that are opposite to each other include a first protrusion 531 and a second protrusion 532, respectively. The first protrusion 531 is slidably disposed in the first limiting notch 513 a. The link-up component 540 has a second limiting notch 541, and the second protrusion 532 is slidably disposed in the second limiting notch 541. Therefore, the holder 410 is for pivoting relative to the display 30 to drive the first assembling component 530 to rotate relative to the pivotal shaft 510. When the first assembling component 530 pivots relative to the pivotal shaft 510, the second protrusion 532 of the first assembling component 530 presses an end of the second limiting notch 541 so as to drive the link-up component 540 to rotate relative to the pivotal shaft 510 with the first assembling component 530.

Moreover, the link-up component 540 includes a hook 542, and the second assembling 550 has a slot 551. The hook 542 is fastened to the slot 551 so that the link-up component 540 is for driving the second assembling component 550 to move with each other. That is, when the first assembling component 530 drives the link-up component 540 to rotate along a direction, the link-up component 540 drives the second assembling component 550 to rotate with the link-up component 540 along the same direction.

The elastic rings 570 surround (i.e., sleeve) the second pivotal section 512. The first locking component 580 is screwed to the second pivotal section 512 so as to interpose the first assembling component 530, the link-up component 540, the second assembling component 550 and the elastic rings 570 between the limiting section 513 and the first locking component 580. The first locking component 580 is for being screwed tightly or loosely so as to adjust a torque for driving the second assembling component 550 to rotate. For example, when the stand 35 supports a heavier display 30, the first locking component 580 can be screwed tightly so as to prevent the second assembling component 550 and support 420 fixed together from rotating due to the weight of the display 30.

The fastening component 560 is securely fastened to the second pivotal section 512, and the second assembling component 550 is located between the fastening component 560 and the link-up component 540.

The first elastic component 600 is, for example, a torsion spring. The first elastic component 600 surrounds the first pivotal section 511. Two ends of the first elastic component 600 that are opposite to each other are fastened to the fixing component 520 and the first assembling component 550, respectively.

The second elastic component 610 is, for example, a torsion spring. The second elastic component 610 surrounds the second pivotal section 512. Two ends of the second elastic component 610 that are opposite to each other are fastened to the fastening component 550 and the second assembling component 560, respectively.

The second locking component 590 is screwed to the second pivoting part 512 so as to interpose the second elastic component 610 and the fastening component 560 between the first locking component 580 and the second locking component 590.

The reinforcement sleeve 620 is riveted to the second assembling component 550. An end of the second elastic component 610 is embedded in the reinforcement sleeve 620 so as to be fixed to the second assembling component 550. A depth of an axial pore of the reinforcement sleeve 620 is much greater than the thickness of the second assembling component 550 so that the second elastic component 610 is fixed to the second assembling component 550 tightly. Therefore, it is favorable for preventing the second elastic component 610 from separating from the second assembling component 550 due to the excess torque applied on the second elastic component 610.

The holder 410 is for pivoting relative to the display 30 via the hinge assembly 50 to have a holding position (as shown in FIG. 4A) and a leaning position (as shown in FIG. 5A), and the support 420 is for pivoting relative to the display 30 to have a storing position (as shown in FIG. 4A) and a supporting position (as shown in FIG. 5A). The rear surface 106 and the holder 410 keep a first angle θ1 therebetween when the holder 410 is located at the holding position. The holder 410 leans against the rear surface 106 when located at the leaning position. When the holder 410 pivots from the holding position to the leaning position, the holder 410 drives the support 420 to pivot with each other so that the support 420 pivots from the storing position to the supporting position. The support 420 leans against the rear surface 106 when located at the storing position. The rear surface 106 and the support 420 keep a second angle θ2 therebetween when the support 420 is located at the supporting position.

To favorably operate the electronic device 3, the torques for driving the first elastic component 600 and the second elastic component 610 can be designed based on the weight of the display 30. For example, in this embodiment, the display 30 is 3 kilograms (kg). The torque for driving the first elastic component 600 to rotate is 4 kg, and the first elastic component 600 normally drives the holder 410 to locate at the leaning position. The torque for driving the second elastic component 610 to rotate is 7 kg, and the second elastic component 610 normally drives the support 420 to locate and position at the storing position. The torque for driving the second elastic component 610 is greater than the torque for driving the first elastic component 600 so that a resultant moment of the two torques forces the holder 410 to locate and position at the holding position. Furthermore, when the support 420 pivots from the storing position to the supporting position, the torque for driving the second elastic component 610 increases from 7 kg to 31 kg, and therefore it is favorable for supporting the display 30 steadily.

Please refer to FIG. 4A, FIG. 4B, FIG. 5A, FIG. 5B, FIG. 6A and FIG. 6B. FIG. 4A is a side view of the electronic device with a holder located at a holding position according to the first embodiment of the disclosure. FIG. 4B is an enlarged cross-sectional view of the electronic device in FIG. 4A. FIG. 5A is a side view of the electronic device with a support located at a supporting position according to the first embodiment of the disclosure. FIG. 5B is an enlarged cross-sectional view of the electronic device in FIG. 5A. FIG. 6A is a side view of the electronic device being pressed in FIG. 5A. FIG. 6B is an enlarged cross-sectional view of the electronic device in FIG. 6A. The holder 410 is located at the holding position, and the support 420 is located at the storing position via the resultant moment of the two torques aforementioned (as shown in FIG. 4A and FIG. 4B).

When a user presses the holder 410 so as to drive the holder 410 to pivot relative to the display 30 from the holding position to the leaning position, the second protrusion 532 of the first assembling component 530 presses the second limiting notch 541 of the link-up component 540. Therefore, the first assembling component 530 drives the link-up component 540 to rotate relative to the pivotal shaft 510, and the link-up component 540 drives the second assembling component 550 and the support 420 fixed together to pivot from the storing position to the supporting position (as shown in FIG. 5A and FIG. 5B).

When the user needs to adjust the angle between the rear surface 106 of the display 30 and the support 420, the user can press the display 30 to increase the second angle θ2 so as to gradually decrease an angle of slope (a degree of inclination) of the display 30.

Please refer to FIG. 7, FIG. 8 and FIG. 9. FIG. 7 is a perspective view of an electronic device according to a second embodiment of the disclosure. FIG. 8 is an exploded view of the electronic device according to the second embodiment of the disclosure. FIG. 9 is another exploded view of the electronic device according to the second embodiment of the disclosure. In this embodiment, an electronic device 1 includes a display 10 and a stand for supporting the electronic device 10. The stand includes two hinge assemblies 11 and a supporting assembly 12. Since the display 10 is similar to the display 30 mentioned in the first embodiment, the following only describes the differences between the display 10 and the display 30.

In this embodiment, a second case 102 of the display 10 has two through holes 102 a. The through hole 102 a extends through two sides of a rear surface 106 of the second case 102 to be connected to an accommodation space 107.

Each of the two hinge assemblies 11 includes a fixing component 111 and an assembling component 112. Each of the two assembling components 112 has a positioning hole 112 a. The fixing component 111 is installed on an assembling plate 103 of the display 10. The assembling component 112 is pivoted on the fixing component 111, and passes through the through hole 102 a of the display 10 to be exposed from the rear surface 106 to the outside.

As shown in FIG. 8, the supporting assembly 12 includes a holder 120 and a support 130 that are integrated together (i.e., integrated into a single piece). The holder 120 and the support 130 are integrated into an annular frame. The holder 120 includes a first connecting section 121, a second connecting section 122 and a third connecting section 123. The first connecting section 121 and the third connecting section 123 are connected to two ends of the second connecting section 122 that are opposite to each other, respectively, so that the first connecting section 121, the second connecting section 122 and the third connecting section 123 together enclose to form a carrying opening 124.

The support 130 includes a fourth connecting section 131, a fifth connecting section 132 and a sixth connecting section 133. The fourth connecting section 131 and the sixth connecting section 133 are connected to two ends of the fifth connecting section 132 that are opposite to each other, respectively. The fourth connecting section 131 is connected to the first connecting section 121 of the holder 120, and the sixth connecting section 133 is connected to the third connecting section 123 of the holder 120. Therefore, the holder 120 and the support 130 can be driven to rotate simultaneously.

Moreover, the fourth connecting section 131 includes a main body 131 a, two sliding rails 131 b and an elastic sheet 131 c. The two sliding rails 131 b are disposed on the main body 131 a. The two sliding rails 131 b together form an inserting groove 131 d. The elastic sheet 131 c is located in the inserting groove 131 d. The sixth connecting section 133 includes a main body 133 a, two sliding rails 133 b and an elastic sheet 133 c. The two sliding rails 133 b are disposed on the main body 133 a. The two sliding rails 133 b together form an inserting groove 133 d. The elastic sheet 133 c is located in the inserting groove 133 d. Moreover, in this embodiment, the elastic sheet 131 c includes a connecting portion 1311 and a fastening portion 1312, and the elastic sheet 133 c includes a connecting portion 1331 and a fastening portion 1332. The connecting portions 1311 and 1331 are disposed on the main bodies 131 a and 133 a, respectively. The fastening portions 1312 and 1332 extend from the main bodies 131 a and 133 a toward the inserting grooves 131 d and 133 d, respectively.

The two assembling components 11 of the two hinge assemblies 112 are inserted into the inserting groove 131 d and 133 d, respectively, so that the fastening portions 1312 and 1332 are detachably fastened to the two holes 112 a, thereby fastening the supporting assembling 12 to the two assembling components 112. Furthermore, the fastening portions 1312 and 1332 can be separated from the two positioning holes 112 a so as to detach the supporting assembling 12 from the assembling components 112.

When the supporting assembly 12 is installed on the assembling components 112, the assembling assembly 12 is for pivoting relative to the display 10. In this embodiment, the holder 120 is for pivoting relative to the display 10 to have a holding position (please refer to FIG. 10 in advance) and a leaning position (please refer to FIG. 11 in advance, which is a side view of the electronic device with a support located at a supporting position according to the second embodiment of the disclosure), and the support 130 is for pivoting relative to the display 10 to have a storing position (as shown in FIG. 10) and a supporting position (as shown in FIG. 11). The rear surface 106 and the holder 120 keep a first angle θ1 therebetween when the holder 120 is located at the holding position. The holder 120 leans against the rear surface 106 when located at the leaning position. When the holder 120 pivots from the holding position to the leaning position, the holder 120 drives the support 130 to pivot with each other so that the support 130 pivots from the storing position to the supporting position. The support 130 leans against the rear surface 106 when located at the storing position. The rear surface 106 and the support 130 keep a second angle θ2 therebetween when the support 130 is located at the supporting position.

Please refer to FIG. 10. FIG. 10 is a side view of the electronic device with a holder located at a holding position according to the second embodiment of the disclosure. In this embodiment, the display 10 has a bottom edge 108. When the electronic device 1 stands on a surface (not shown in the drawings) via the support 130, the bottom edge 108 leans against the surface. The surface is, for example, a top surface of a desk. The supporting assembly 12 is for pivoting relative to the display 10 along an axis A parallel to the bottom edge 108. There is a distance L between the axis A and the bottom edge 108 (in other words, there is a distance L between an axis of the rotation of the hinge assembly 11 and the bottom edge 108) so as to prevent the display 10 from collapsing. In this embodiment, the distance L is 0.5 times greater than a height H of the display 10, but is 0.75 times less than the height H (that is, 0.5H<L<0.75H). Therefore, the electronic device 1 can stably stand on the surface. The disclosure is not limited to the foregoing ratio of the distance L to the height H. In some other embodiments, the ratio of the distance L to the height H can be adjusted based on the weight of the display 10.

Furthermore, when the support 130 is located at the storing position, there is a distance D1 between an edge of the second connecting section 122 close to the support 130 and the rear surface 106, the second connecting section 122 has a width D2, both of the first connecting section 121 and the third connecting section 123 have a length D3, the holder 120 and the rear surface 106 keep the first angle θ1 therebetween, and the following condition is satisfied: cot θ1=D1/(D3−D2). Therefore, the user is able to favorably insert his/her hand through the carrying opening 124 to carry the electronic device 1. In this embodiment, the distance D1 is larger than 18 cm, the width D2 is larger than 20 cm, and the length D3 is larger than 60 cm, but the disclosure is not limited thereto. In some other embodiments, the distance D1, the width D2 and the length D3 can be any value, respectively, without taking into account the operation and movement of the electronic device 1.

Furthermore, the electronic device 1 further includes a first magnetic component 13 and a second magnetic component 14. The first magnetic component 13 is located at the rear surface 106 of the display 10, and the second magnetic component 14 is located at the support 130. The first magnetic component 13 and the second magnetic component 14 are for attracting to each other.

Please refer to FIG. 10 and FIG. 11. As shown in FIG. 10, the first magnetic component 13 attracts the second magnetic component 14 so as to locate the support 130 and the holder 120 at the storing position and the holding position, respectively. The user can carry the electronic device 1 by directly inserting his/her hand through the carrying opening 124 to hold the holder 120.

When the user needs to stand the electronic device on the surface, the user presses the display 10 and the holder 120 simultaneously with one hand (for example, a thumb and a forefinger). When a force applied to press the display 10 and the holder 120 is greater than the attraction between the first magnetic component 13 and the second magnetic component 14, the holder 120 pivots relative to the display 10 from the holding position to the leaning position. The holder 120 drives the support 130 to pivot from the storing position to the supporting position (as shown in FIG. 11). Therefore, the electronic device 1 can stand on the surface of the desk via the support 130.

To sum up, the user carries the electronic device 1, rotating the support 130, standing the electronic device 1 on the supporting surface with only one hand. Therefore, it is favorable for operating the electronic device 1 more conveniently.

Furthermore, when the two assembling components 112 are inserted into the inserting grooves 131 d and 133 d, respectively, the first case 101 and the supporting assembly 12 interpose the second case 102 so as to allow the first case 101 and the second case 102 to tightly assemble with each other.

Moreover, in this embodiment, the electronic device 1 can be hung on a wall 4 instead of standing on the surface of a desk. Please refer to FIG. 12, which is a side view of the electronic device disposed on a wall according to the second embodiment of the disclosure. When the electronic device 1 stands on the surface, a field of view of the electronic device 1 is limited (referring to FIG. 11). Therefore, as shown in FIG. 112, to watch programs, shows or look at images by the display 10 more comfortably, the user presses the elastic sheet 131 c and 133 c to separate the display 10 from the supporting assembly 12. A rack 5 is installed on the wall 4, and has two grooves corresponding to the two assembling components 112. The two assembling components 112 are inserted into the rack 5 so as to install the display 10 on the wall 4.

The holder and the support of the supporting assembly can be two individual units. Please refer to FIG. 13, FIG. 14A and FIG. 14B. FIG. 13 is a perspective view of an electronic device according to a third embodiment. FIG. 14A is an exploded view of the electronic device according to the third embodiment. FIG. 14B is an enlarged view of a hinge assembly in FIG. 14A. Since this embodiment is similar to the second embodiment, the following only describes the differences. In this embodiment, an electronic device 2 includes a display 20, two hinge assemblies 21 and a supporting assembly 22. Each of the two hinge assemblies 21 includes a fixing component 211, a first assembling component 212, a second assembling component 213 and a blocking component 214. The fixing component 211 is installed on the display 20. Both of the first assembling component 212 and the second assembling component 213 are pivoted on the fixing component 211. The first assembling component 212 and the second assembling component 213 are for pivoting relative to the display 10 along an axis A. The blocking component 214 is securely fixed to the first assembling component 212. The supporting assembly 22 includes a holder 220 and a support 230 that are two individual units (that is, being not integrated into a single unit). The holder 220 has two first inserting grooves 221 a, and the support 230 has two second inserting grooves 231 a. The first assembling component 212 and the second assembling component 213 are inserted into the first inserting groove 221 a and the second inserting groove 231 a, respectively, so that the blocking component 214 is located between the display 20 and the support 230. When the holder 220 pivots relative to the display 20 from a holding position to a leaning position, the first assembling component 212 drives the blocking component 214 to rotate with each other. The blocking component 214 presses the second assembling component 213 so as to drive the support 230 to pivot relative to the holder 220 from a storing position to a supporting position.

Please refer to FIG. 15 and FIG. 16. FIG. 15 is a side view of the electronic device with a support located at a supporting position according to the third embodiment of the disclosure. FIG. 16 is a side view of pressing the electronic device in FIG. 15. In this embodiment, when the electronic device 2 stands on a supporting surface via the support 230, the support 230 and the display 20 keep an angle θ3 therebetween (as shown in FIG. 15). The user presses the display 20 to increase the angle θ3 (as shown in FIG. 16) so that it is favorable for adjusting an angle of slope of the display 20 under different usage conditions.

To sum up, in the second embodiment, the hinge assembly 11 includes only one assembling component 112, and the holder 120 and the support 130 are integrated into a single unit (as shown in FIG. 7). Therefore, the angle between the support 130 and the display 10 is fixed. However, in this embodiment, the hinge assembly 21 includes the first assembling component 530 and the second assembling component 550 that are for rotating independently, and the holder 220 and the support 230 are two separated and individual units (as shown in FIG. 13 and FIG. 14A). Therefore, the angle between the support 230 and the display 20 is adjustable.

The number of assembling components, that of the inserting groove and that of the blocking component can only be one. Please refer to FIG. 17. FIG. 17 is an exploded view of an electronic device according to the fourth embodiment. Since this embodiment is similar to the third embodiment, the following only describes the differences. In this embodiment, the hinge assembly 21 includes only one first assembling component 212, only one second assembling component 213 and only one blocking component 214. The holder 220 has only one first inserting groove 221 a, and the support 230 has only one second inserting groove 231 a. The holder 220 further includes a seventh connecting section 224.
